SIASUN(SZ:300024)2025-08-26 15:02Summary of Industry Research on Humanoid Robots Industry Overview - The humanoid robot industry is transitioning from intelligent development to large-scale application, leading to a significant increase in demand for upstream materials, particularly in AI applications and body materials, with a core requirement for lightweight materials [2][4] Key Materials and Their Applications - High-end Engineering Plastics: - PEEK (Polyether Ether Ketone): Used for robot skeletons, known for high strength and stability, with global production mainly concentrated in the UK [5] - PA (Polyamide): Commonly used for mechanical components, offering good toughness and wear resistance, applicable via 3D printing [5] - PPS (Polyphenylene Sulfide): A substitute for PEEK, slightly lower in performance but more cost-effective, primarily used in automotive and electrical applications [5] - LCP (Liquid Crystal Polymer): Widely used in core components like servo motor connectors, known for good processing performance and stability, with production concentrated in Japan and the US [5] - TPE (Thermoplastic Elastomer): Versatile with applications across automotive, electrical, construction, and consumer goods, expected to reach a market size of over $24 billion in three years with a 6% CAGR [5] Market Dynamics - The domestic market leans towards mass materials, while the overseas market focuses on fine chemicals and high-end products, indicating a need for time in import substitution [6] - Ultra-high molecular weight polyethylene (UHMWPE) is gaining traction in mechanical materials, with a global production growth rate of approximately 15% annually, and domestic growth expected to be faster [6][7] Carbon Fiber Trends - Carbon fiber was widely used in robotic arms but has seen a demand decline since 2023, with current applications shifting towards the wind power sector. Despite rapid capacity expansion, poor supply-demand conditions have led to lower prices, though future demand increases and improved supply-demand dynamics are expected to support industry growth [8][9] Electronic Skin and Flexible Sensors - Electronic skin utilizes flexible sensors to recognize pressure, with the global flexible sensor market projected to grow from $1.5 billion in 2022 to $5.3 billion by 2029, at an 18% CAGR. Domestic companies are accelerating their layouts, aiming for domestic substitution [10] Investment Recommendations - Focus on lightweight reduction through high-end engineering plastics and carbon fiber, as well as perception and interaction through electronic skin-related sensors and flexible substrates. Key companies to watch include Ruihuatai, Xin'an, and Xinfang, along with other firms with strong capabilities in these segments [12][13]
